It also feels like Stasi era nonsense. If someone borrows my phone, must I record the call?

[mahouse]

Yes obviously, how do you prove it was not you who made the call?

[scotty79]

Voice? Being provably somewhere else when the call was made?

[mahouse]

Voice -> it is not recorded by default by anybody unless you are under the spotlight.

Prove you are somewhere else -> can you prove you were somewhere else 24/7? I bet you can not.

[scotty79]

If you don't have the voice then you can't say I made the call. Only that it came from phone registered to me. I can't disprove that if that happened.

No, but the contents will be attributed to you...
